A naturally isolated cell-permeable fungal resorcylic lactone that acts as a selective and highly potent inhibitor against the MAPKKK TAK1 activity (IC50 = 8 nM) in an ATP-competitive and irreversible manner, while inhibiting MEK1 (IC50 = 411 nM) and three other MAPKKKs (IC50 ≥268 nM against MEKK1, ASK1, and MEKK4) only at much higher concentrations. Shown to inhibit IL-1-induced/TAK1-mediated, but not H2O2-induced/TAK1-independent, JNK and p38 phosphorylation in 293 cells. (5Z)-Zeaenol, Curvularia sp. (Cat. No. 499609) may serve as a negative control.
